FIELD

The present disclosure generally relates to organometallic compounds andformulations and their various uses including as emitters in devicessuch as organic light emitting diodes and related electronic devices.

BACKGROUND

Opto-electronic devices that make use of organic materials are becomingincreasingly desirable for various reasons. Many of the materials usedto make such devices are relatively inexpensive, so organicopto-electronic devices have the potential for cost advantages overinorganic devices. In addition, the inherent properties of organicmaterials, such as their flexibility, may make them well suited forparticular applications such as fabrication on a flexible substrate.Examples of organic opto-electronic devices include organic lightemitting diodes/devices (OLEDs), organic phototransistors, organicphotovoltaic cells, and organic photodetectors. For OLEDs, the organicmaterials may have performance advantages over conventional materials.

OLEDs make use of thin organic films that emit light when voltage isapplied across the device. OLEDs are becoming an increasinglyinteresting technology for use in applications such as flat paneldisplays, illumination, and backlighting.

One application for phosphorescent emissive molecules is a full colordisplay. Industry standards for such a display call for pixels adaptedto emit particular colors, referred to as “saturated” colors. Inparticular, these standards call for saturated red, green, and bluepixels. Alternatively, the OLED can be designed to emit white light. Inconventional liquid crystal displays emission from a white backlight isfiltered using absorption filters to produce red, green and blueemission. The same technique can also be used with OLEDs. The white OLEDcan be either a single emissive layer (EML) device or a stack structure.Color may be measured using CIE coordinates, which are well known to theart.

DETAILED DESCRIPTION A. Terminology

Unless otherwise specified, the below terms used herein are defined asfollows:

As used herein, the term “organic” includes polymeric materials as wellas small molecule organic materials that may be used to fabricateorganic opto-electronic devices. “Small molecule” refers to any organicmaterial that is not a polymer, and “small molecules” may actually bequite large. Small molecules may include repeat units in somecircumstances. For example, using a long chain alkyl group as asubstituent does not remove a molecule from the “small molecule” class.Small molecules may also be incorporated into polymers, for example as apendent group on a polymer backbone or as a part of the backbone. Smallmolecules may also serve as the core moiety of a dendrimer, whichconsists of a series of chemical shells built on the core moiety. Thecore moiety of a dendrimer may be a fluorescent or phosphorescent smallmolecule emitter. A dendrimer may be a “small molecule,” and it isbelieved that all dendrimers currently used in the field of OLEDs aresmall molecules.

As used herein, “top” means furthest away from the substrate, while“bottom” means closest to the substrate. Where a first layer isdescribed as “disposed over” a second layer, the first layer is disposedfurther away from substrate. There may be other layers between the firstand second layer, unless it is specified that the first layer is “incontact with” the second layer. For example, a cathode may be describedas “disposed over” an anode, even though there are various organiclayers in between.

As used herein, “solution processable” means capable of being dissolved,dispersed, or transported in and/or deposited from a liquid medium,either in solution or suspension form.

A ligand may be referred to as “photoactive” when it is believed thatthe ligand directly contributes to the photoactive properties of anemissive material. A ligand may be referred to as “ancillary” when it isbelieved that the ligand does not contribute to the photoactiveproperties of an emissive material, although an ancillary ligand mayalter the properties of a photoactive ligand

As used herein, and as would be generally understood by one skilled inthe art, a first “Highest Occupied Molecular Orbital” (HOMO) or “LowestUnoccupied Molecular Orbital” (LUMO) energy level is “greater than” or“higher than” a second HOMO or LUMO energy level if the first energylevel is closer to the vacuum energy level. Since ionization potentials(IP) are measured as a negative energy relative to a vacuum level, ahigher HOMO energy level corresponds to an IP having a smaller absolutevalue (an IP that is less negative). Similarly, a higher LUMO energylevel corresponds to an electron affinity (EA) having a smaller absolutevalue (an EA that is less negative). On a conventional energy leveldiagram, with the vacuum level at the top, the LUMO energy level of amaterial is higher than the HOMO energy level of the same material. A“higher” HOMO or LUMO energy level appears closer to the top of such adiagram than a “lower” HOMO or LUMO energy level.

As used herein, and as would be generally understood by one skilled inthe art, a first work function is “greater than” or “higher than” asecond work function if the first work function has a higher absolutevalue. Because work functions are generally measured as negative numbersrelative to vacuum level, this means that a “higher” work function ismore negative. On a conventional energy level diagram, with the vacuumlevel at the top, a “higher” work function is illustrated as furtheraway from the vacuum level in the downward direction. Thus, thedefinitions of HOMO and LUMO energy levels follow a different conventionthan work functions.

In yet other instances, the most preferred general substituents areselected from the group consisting of deuterium, fluorine, alkyl,cycloalkyl, aryl, heteroaryl, and combinations thereof.

The terms “substituted” and “substitution” refer to a substituent otherthan H that is bonded to the relevant position, e.g., a carbon ornitrogen. For example, when R¹ represents mono-substitution, then one R¹must be other than H (i.e., a substitution). Similarly, when R¹represents di-substitution, then two of R¹ must be other than H.Similarly, when R¹ represents zero or no substitution, R¹, for example,can be a hydrogen for available valencies of ring atoms, as in carbonatoms for benzene and the nitrogen atom in pyrrole, or simply representsnothing for ring atoms with fully filled valencies, e.g., the nitrogenatom in pyridine. The maximum number of substitutions possible in a ringstructure will depend on the total number of available valencies in thering atoms.

As used herein, “combinations thereof” indicates that one or moremembers of the applicable list are combined to form a known orchemically stable arrangement that one of ordinary skill in the art canenvision from the applicable list. For example, an alkyl and deuteriumcan be combined to form a partial or fully deuterated alkyl group; ahalogen and alkyl can be combined to form a halogenated alkylsubstituent; and a halogen, alkyl, and aryl can be combined to form ahalogenated arylalkyl. In one instance, the term substitution includes acombination of two to four of the listed groups. In another instance,the term substitution includes a combination of two to three groups.

Preferred combinations of substituent groups are those thatcontain up to fifty atoms that are not hydrogen or deuterium, or thosewhich include up to forty atoms that are not hydrogen or deuterium, orthose that include up to thirty atoms that are not hydrogen ordeuterium. In many instances, a preferred combination of substituentgroups will include up to twenty atoms that are not hydrogen ordeuterium.

The “aza” designation in the fragments described herein, i.e.aza-dibenzofuran, aza-dibenzothiophene, etc. means that one or more ofthe C—H groups in the respective aromatic ring can be replaced by anitrogen atom, for example, and without any limitation, azatriphenyleneencompasses both dibenzo[f,h]quinoxaline and dibenzo[f,h]quinoline. Oneof ordinary skill in the art can readily envision other nitrogen analogsof the aza-derivatives described above, and all such analogs areintended to be encompassed by the terms as set forth herein.

As used herein, “deuterium” refers to an isotope of hydrogen. Deuteratedcompounds can be readily prepared using methods known in the art. Forexample, U.S. Pat. No. 8,557,400, Patent Pub. No. WO 2006/095951, andU.S. Pat. Application Pub. No. US 2011/0037057, which are herebyincorporated by reference in their entireties, describe the making ofdeuterium-substituted organometallic complexes. Further reference ismade to Ming Yan, et al., Tetrahedron 2015, 71, 1425-30 and Atzrodt etal., Angew. Chem. Int. Ed. (Reviews) 2007, 46, 7744-65, which areincorporated by reference in their entireties, describe the deuterationof the methylene hydrogens in benzyl amines and efficient pathways toreplace aromatic ring hydrogens with deuterium, respectively.

It is to be understood that when a molecular fragment is described asbeing a substituent or otherwise attached to another moiety, its namemay be written as if it were a fragment (e.g. phenyl, phenylene,naphthyl, dibenzofuryl) or as if it were the whole molecule (e.g.benzene, naphthalene, dibenzofuran). As used herein, these differentways of designating a substituent or attached fragment are considered tobe equivalent.

In some instance, a pair of adjacent substituents can be optionallyjoined or fused into a ring. The preferred ring is a five, six, orseven-membered carbocyclic or heterocyclic ring, includes both instanceswhere the portion of the ring formed by the pair of substituents issaturated and where the portion of the ring formed by the pair ofsubstituents is unsaturated. As used herein, “adjacent” means that thetwo substituents involved can be on the same ring next to each other, oron two neighboring rings having the two closest available substitutablepositions, such as 2, 2′ positions in a biphenyl, or 1, 8 position in anaphthalene, as long as they can form a stable fused ring system.

In yet another aspect, the OLED of the present disclosure may alsocomprise an emissive region containing a compound as disclosed in theabove compounds section of the present disclosure.

In some embodiments, the emissive region can comprise a compound of

wherein: R^(A) and R^(B) each independently represents zero, mono, or upto the maximum allowed number of substitutions to its associated ring;R¹, R², R³, and R⁴ are each independently a hydrogen or a substituentselected from the group consisting of deuterium, alkyl, heteroalkyl,cycloalkyl, heterocycloalkyl, and combinations thereof; each R^(A) andR^(B) is independently a hydrogen or a substituent selected from thegroup consisting of the general substituents described herein; the totalnumber of carbon atoms comprised by R¹, R², R³, and R⁴ is greater thanor equal to 10; and X is CH₃, CH₂D, CHD₂, or CD₃.

In some embodiments, at least one of the anode, the cathode, or a newlayer disposed over the organic emissive layer functions as anenhancement layer. The enhancement layer comprises a plasmonic materialexhibiting surface plasmon resonance that non-radiatively couples to theemitter material and transfers excited state energy from the emittermaterial to non-radiative mode of surface plasmon polariton. Theenhancement layer is provided no more than a threshold distance awayfrom the organic emissive layer, wherein the emitter material has atotal non-radiative decay rate constant and a total radiative decay rateconstant due to the presence of the enhancement layer and the thresholddistance is where the total non-radiative decay rate constant is equalto the total radiative decay rate constant. In some embodiments, theOLED further comprises an outcoupling layer. In some embodiments, theoutcoupling layer is disposed over the enhancement layer on the oppositeside of the organic emissive layer. In some embodiments, the outcouplinglayer is disposed on opposite side of the emissive layer from theenhancement layer but still outcouples energy from the surface plasmonmode of the enhancement layer. The outcoupling layer scatters the energyfrom the surface plasmon polaritons. In some embodiments this energy isscattered as photons to free space. In other embodiments, the energy isscattered from the surface plasmon mode into other modes of the devicesuch as but not limited to the organic waveguide mode, the substratemode, or another waveguiding mode. If energy is scattered to thenon-free space mode of the OLED other outcoupling schemes could beincorporated to extract that energy to free space. In some embodiments,one or more intervening layer can be disposed between the enhancementlayer and the outcoupling layer. The examples for interventing layer(s)can be dielectric materials, including organic, inorganic, perovskites,oxides, and may include stacks and/or mixtures of these materials.

The enhancement layer modifies the effective properties of the medium inwhich the emitter material resides resulting in any or all of thefollowing: a decreased rate of emission, a modification of emissionline-shape, a change in emission intensity with angle, a change in thestability of the emitter material, a change in the efficiency of theOLED, and reduced efficiency roll-off of the OLED device. Placement ofthe enhancement layer on the cathode side, anode side, or on both sidesresults in OLED devices which take advantage of any of theabove-mentioned effects. In addition to the specific functional layersmentioned herein and illustrated in the various OLED examples shown inthe figures, the OLEDs according to the present disclosure may includeany of the other functional layers often found in OLEDs.

The enhancement layer can be comprised of plasmonic materials, opticallyactive metamaterials, or hyperbolic metamaterials. As used herein, aplasmonic material is a material in which the real part of thedielectric constant crosses zero in the visible or ultraviolet region ofthe electromagnetic spectrum. In some embodiments, the plasmonicmaterial includes at least one metal. In such embodiments the metal mayinclude at least one of Ag, Al, Au, Ir, Pt, Ni, Cu, W, Ta, Fe, Cr, Mg,Ga, Rh, Ti, Ru, Pd, In, Bi, Ca alloys or mixtures of these materials,and stacks of these materials. In general, a metamaterial is a mediumcomposed of different materials where the medium as a whole actsdifferently than the sum of its material parts. In particular, we defineoptically active metamaterials as materials which have both negativepermittivity and negative permeability. Hyperbolic metamaterials, on theother hand, are anisotropic media in which the permittivity orpermeability are of different sign for different spatial directions.Optically active metamaterials and hyperbolic metamaterials are strictlydistinguished from many other photonic structures such as DistributedBragg Reflectors (“DBRs”) in that the medium should appear uniform inthe direction of propagation on the length scale of the wavelength oflight. Using terminology that one skilled in the art can understand: thedielectric constant of the metamaterials in the direction of propagationcan be described with the effective medium approximation. Plasmonicmaterials and metamaterials provide methods for controlling thepropagation of light that can enhance OLED performance in a number ofways.

In some embodiments, the enhancement layer is provided as a planarlayer. In other embodiments, the enhancement layer has wavelength-sizedfeatures that are arranged periodically, quasi-periodically, orrandomly, or sub-wavelength-sized features that are arrangedperiodically, quasi-periodically, or randomly. In some embodiments, thewavelength-sized features and the sub-wavelength-sized features havesharp edges.

In some embodiments, the outcoupling layer has wavelength-sized featuresthat are arranged periodically, quasi-periodically, or randomly, orsub-wavelength-sized features that are arranged periodically,quasi-periodically, or randomly. In some embodiments, the outcouplinglayer may be composed of a plurality of nanoparticles and in otherembodiments the outcoupling layer is composed of a plurality ofnanoparticles disposed over a material. In these embodiments theoutcoupling may be tunable by at least one of varying a size of theplurality of nanoparticles, varying a shape of the plurality ofnanoparticles, changing a material of the plurality of nanoparticles,adjusting a thickness of the material, changing the refractive index ofthe material or an additional layer disposed on the plurality ofnanoparticles, varying a thickness of the enhancement layer, and/orvarying the material of the enhancement layer. The plurality ofnanoparticles of the device may be formed from at least one of metal,dielectric material, semiconductor materials, an alloy of metal, amixture of dielectric materials, a stack or layering of one or morematerials, and/or a core of one type of material and that is coated witha shell of a different type of material.

In some embodiments, the consumer product can be one of a flat paneldisplay, a computer monitor, a medical monitor, a television, abillboard, a light for interior or exterior illumination and/orsignaling, a heads-up display, a fully or partially transparent display,a flexible display, a laser printer, a telephone, a cell phone, tablet,a phablet, a personal digital assistant (PDA), a wearable device, alaptop computer, a digital camera, a camcorder, a viewfinder, amicro-display that is less than 2 inches diagonal, a 3-D display, avirtual reality or augmented reality display, a vehicle, a video wallcomprising multiple displays tiled together, a theater or stadiumscreen, a light therapy device, and a sign.

Generally, an OLED comprises at least one organic layer disposed betweenand electrically connected to an anode and a cathode. When a current isapplied, the anode injects holes and the cathode injects electrons intothe organic layer(s). The injected holes and electrons each migratetoward the oppositely charged electrode. When an electron and holelocalize on the same molecule, an “exciton,” which is a localizedelectron-hole pair having an excited energy state, is formed. Light isemitted when the exciton relaxes via a photoemissive mechanism. In somecases, the exciton may be localized on an excimer or an exciplex.Non-radiative mechanisms, such as thermal relaxation, may also occur,but are generally considered undesirable.

Several OLED materials and configurations are described in U.S. Pat.Nos. 5,844,363, 6,303,238, and 5,707,745, which are incorporated hereinby reference in their entirety.

The initial OLEDs used emissive molecules that emitted light from theirsinglet states (“fluorescence”) as disclosed, for example, in U.S. Pat.No. 4,769,292, which is incorporated by reference in its entirety.Fluorescent emission generally occurs in a time frame of less than 10nanoseconds.

FIG. 2 provides oneexample of how some layers may be omitted from the structure of device100.

The simple layered structure illustrated in FIGS. 1 and 2 is provided byway of non-limiting example, and it is understood that embodiments ofthe present disclosure may be used in connection with a wide variety ofother structures. The specific materials and structures described areexemplary in nature, and other materials and structures may be used.Functional OLEDs may be achieved by combining the various layersdescribed in different ways, or layers may be omitted entirely, based ondesign, performance, and cost factors. Other layers not specificallydescribed may also be included. Materials other than those specificallydescribed may be used. Although many of the examples provided hereindescribe various layers as comprising a single material, it isunderstood that combinations of materials, such as a mixture of host anddopant, or more generally a mixture, may be used. Also, the layers mayhave various sublayers. The names given to the various layers herein arenot intended to be strictly limiting. For example, in device 200, holetransport layer 225 transports holes and injects holes into emissivelayer 220, and may be described as a hole transport layer or a holeinjection layer. In one embodiment, an OLED may be described as havingan “organic layer” disposed between a cathode and an anode. This organiclayer may comprise a single layer, or may further comprise multiplelayers of different organic materials as described, for example, withrespect to FIGS. 1 and 2.

OLEDs may be stacked, for example asdescribed in U.S. Pat. No. 5,707,745 to Forrest et al, which isincorporated by reference in its entirety. The OLED structure maydeviate from the simple layered structure illustrated in FIGS. 1 and 2.For example, the substrate may include an angled reflective surface toimprove out-coupling, such as a mesa structure as described in U.S. Pat.No. 6,091,195 to Forrest et al., and/or a pit structure as described inU.S. Pat. No. 5,834,893 to Bulovic et al., which are incorporated byreference in their entireties.

No. 7,431,968, which is incorporated by reference in itsentirety. Other suitable deposition methods include spin coating andother solution based processes. Solution based processes are preferablycarried out in nitrogen or an inert atmosphere. For the other layers,preferred methods include thermal evaporation. Preferred patterningmethods include deposition through a mask, cold welding such asdescribed in U.S. Pat.

Other methods may also be used. The materials to bedeposited may be modified to make them compatible with a particulardeposition method. For example, substituents such as alkyl and arylgroups, branched or unbranched, and preferably containing at least 3carbons, may be used in small molecules to enhance their ability toundergo solution processing. Substituents having 20 carbons or more maybe used, and 3-20 carbons are a preferred range. Materials withasymmetric structures may have better solution processability than thosehaving symmetric structures, because asymmetric materials may have alower tendency to recrystallize Dendrimer substituents may be used toenhance the ability of small molecules to undergo solution processing.

One purposeof the barrier layer is to protect the electrodes and organic layersfrom damaging exposure to harmful species in the environment includingmoisture, vapor and/or gases, etc. The barrier layer may be depositedover, under or next to a substrate, an electrode, or over any otherparts of a device including an edge. The barrier layer may comprise asingle layer, or multiple layers. The barrier layer may be formed byvarious known chemical vapor deposition techniques and may includecompositions having a single phase as well as compositions havingmultiple phases.

Device Data

All example devices were fabricated by high vacuum (<10⁻⁷ Torr) thermalevaporation. The anode electrode was 800 Å of indium tin oxide (ITO).The cathode consisted of 10 Å of Liq (8-hydroxyquinoline lithium)followed by 1,000 Å of Al. All devices were encapsulated with a glasslid sealed with an epoxy resin in a nitrogen glove box (<1 ppm of H₂Oand O₂) immediately after fabrication with a moisture getterincorporated inside the package. The organic stack of the deviceexamples consisted of sequentially, from the ITO Surface: 100 Å ofHAT-CN as the hole injection layer (HIL); 450 Å of HTM as a holetransporting layer (HTL); emissive layer (EML) with thickness 400 Å.Emissive layer containing H-host (H1): E-host (H2) in 6:4 ratio and 12weight % of green emitter. 350 Å of Liq (8-hydroxyquinoline lithium)doped with 40% of ETM as the ETL. Device structure is shown in thetable 1. Table 1 shows the schematic device structure. The chemicalstructures of the device materials are shown below.

Upon fabrication, the devices were measured for electro luminescence(EL), JVL and lifetested at DC 80 mA/cm². LT97 at 1,000 nits wascalculated from 80 mA/cm2 LT data assuming acceleration factor 1.8.Device performance is shown in the Table 2.

The above data shows that the Inventive Examples 1 and 2 exhibited lowervoltage, higher efficiency, and longer lifetime relative to theComparative Examples 1 and 2, respectively. The improvements of 11-14%of the relative EQE and 27-52% of lifetime are above any value thatcould be attributed to experimental error and the observed improvementsare significant. Based on the fact that the Comparative Compounds 1 and2 have a similar structure as the inventive compounds with the onlydifference being that the 2-phenylpyridine moiety is not furthersubstituted, the significant performance improvement observed in theabove data was unexpected. Without being bound by any theories, thisimprovement may attribute to the better alignment with transitiondipolar moment of the inventive molecules.
